Corrective action
Adjust brightness with software.
If this is not possible, retake
image at lower exposure. See
exposure guidelines Section 5.1.
Increase the amount of time
that is used to erase plates.
Alternatively, increase the inten-
sity of the light source. To test if
an imaging plate is completely
erased, simply mount an erased
plate on a carousel and scan it.
If no image is obtained, your
procedure is effective at com-
pletely erasing imaging plates.
Insure the imaging plates are
inserted properly into the barri-
er envelope and the proper ori-
entation to the X-ray source is
maintained
Do not store imaging plates in
barrier envelopes for more than
one week.
Do not leave exposed imaging
plates in well-lit areas. Even in
the barrier envelope, some light
penetrates and can partially
erase the imaging plates.
Transfer imaging plates from
their protective barriers to the
DenOptix QST scanner as quickly
as possible using the Dark Box
(within one hour of exposure).
